The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0033] It is understood that spatial relation terms such as “below,” “under,” “below,” “below,” “above,” “above,” etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as “below,” “below,” or “below” will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.
[0034] Example 1
[0035] A vehicle-mounted flight unit, such as Figure 1 and Figure 2 As shown, it includes a fuselage 1, a mounting base 2, two front fixed wings 7, two tilting wings 8, and two rear fixed wings 9. The mounting base 2 is located on the top of the fuselage 1.
[0036] Two front fixed wings 7 are symmetrically arranged on the left and right sides of the front end of the mounting base 2. Each front fixed wing 7 includes a front fixed rod 71 and a front rotor 72. The front rotor 72 is located at one end of the front fixed rod 71, and the other end of the front fixed rod 71 is connected to the mounting base 2.
[0037] Two rear fixed wings 9 are symmetrically arranged on the left and right sides of the rear end of the mounting base 2. Each rear fixed wing 9 includes a rear fixed rod 91 and a rear rotor 92. The rear rotor 92 is located at one end of the rear fixed rod 91, and the other end of the rear fixed rod 91 is connected to the mounting base 2.
[0038] Two rotating wings 8 are symmetrically arranged on the left and right sides of the middle of the mounting base 2. Each rotating wing 8 includes a rotating rod 81 and a duct 82. The duct 82 is located at one end of the rotating rod 81, and the other end of the rotating rod 81 is rotatably connected to the mounting base 2 through a rotating mechanism 3, which is used to switch the duct 82 between horizontal and vertical orientations.
[0039] In this embodiment, as Figure 3 As shown, the rotating mechanism 3 includes a dual-axis tilting motor 31 and a motor bracket 32. The dual-axis tilting motor 31 is mounted in the mounting base 2 via the motor bracket 32. The two tilting rods 81 are coaxially connected to the two output shafts of the dual-axis tilting motor 31. Both output shafts of the dual-axis tilting motor 31 are equipped with angle sensors to detect the tilting angle of the duct 82.
[0040] This embodiment incorporates a reversible duct 82. During takeoff and landing, the duct 82 flips to a vertical orientation to provide ground thrust, thus achieving vertical takeoff and landing. During level flight, the duct 82 flips to a horizontal orientation to provide propulsion for forward, backward, left, and right flight. Furthermore, through the combination of the duct 82 and the rotors, the two front rotors 72 and the two rear rotors 92 provide vertical balancing forces, ensuring stable flight of the vehicle-mounted flight unit.

[0042] The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, the mounting base 2 is provided with two front mounting brackets 4, two middle mounting brackets 5 and two rear mounting brackets.
[0043] Two front mounting brackets 4 are symmetrically arranged on the left and right sides of the front end of the mounting base 2, and the front fixing rod 71 is detachably inserted into the front mounting bracket 4. Figure 5 As shown, a first clamp 41 extending out of the mounting base 2 is provided on one side of the front mounting bracket 4, and a first tightening groove 42 extending to the bottom of the first clamp 41 is provided. The first clamp 41 is used to clamp the front fixing rod 71.

The two fixed frames 52 are symmetrically arranged on the left and right sides of the center of the mounting base 2. The rotating body is a hollow tube and is rotatably inserted into the fixed frame 52. One end of the rotating body is coaxially connected to the output shaft of the dual-axis flip motor 31, and the flip rod 81 is coaxially and detachably inserted into the other end of the rotating body. One end of the rotating body connected to the flip rod 81 extends out of the mounting base 2 and is provided with a second clamp 53. The bottom of the second clamp 53 is provided with a second tightening groove 54 extending to the rotating body. The central clamp is used to clamp the flip rod 81.
[0045] Two rear-end mounting brackets 6 are symmetrically arranged on the left and right sides of the rear end of the mounting base 2, and the rear fixing rod 91 is detachably inserted into the rear-end mounting brackets 6. Figure 7 As shown, a third clamp 61 extending from the mounting base 2 is provided on one side of the rear mounting bracket 6, and a third tightening groove 62 extending to the rear mounting bracket 6 is provided at the bottom of the third clamp 61.
